Definitions

  • the present invention relates to a transparent fire protection glazing with burglary-resistant and antipanic properties, a method for production thereof, and use thereof.
  • fire protection glazings is generally understood to mean components that are made of one or a plurality of light-permeable systems that are mounted in a frame with holders and seals.
  • EI fire resistance
  • Such glazings are additionally characterized by the indication of the duration of their fire resistance in minutes (e.g.: EI 30, EI 90, E 30, EI 120).
  • E glazings prevent only the spread of fire and smoke for the corresponding time.
  • EI glazings must prevent the passage of heat radiation.
  • EI glazings are combined systems of fire protection panes and fill layers between the panes.
  • the fill layers foam in the event of fire and thus act as a heat shield.
  • the foaming is also referred to as intumescence.
  • These fill layers can be either organic or inorganic or a combination of the two. Their task is to delay the transfer of heat, on the one hand, by endothermic processes, such as vaporization in the fill layers; on the other, forming an insulating residue, such as foam, which is intended to adhere well to the glass.
  • German patent application DE 10 2010 037 966 A1 is a monolithic, attack resistant, and fire-resistant glazing.
  • This glazing has at least one intumescent fire protection layer, wherein at least one plastic layer (plastic pane) is arranged in each case directly or indirectly on the opposite side surfaces of the fire protection glazing. At least one glass or glass ceramic pane is arranged in each case on the sides of the plastic layer facing away from the fire protection glazing.
  • plastic pane plastic pane
  • At least one glass or glass ceramic pane is arranged in each case on the sides of the plastic layer facing away from the fire protection glazing.
  • Fire protection glazings are frequently intended to be used in so-called “antipanic glazings”. This means doors that, even in the locked state, can be opened from one direction, typically outward from the interior of the building involved, for example, by an opening such that they open the way for escaping crowds out of the interior. Special penetration resistant properties must be provided on such a glazing because the opening lever is accessible from the outside through the creation of a relatively small hole by which means the door can also be opened from the outside.
  • WO 2005/115746 A1 discloses complex fire protection glazings that can be made of fire protection units connected to one another that consist in each case of a plurality of glass panes connected to one another via intumescent layers.
  • the fire protection glazings have no plastic panes to increase burglary resistance. Their burglary-resistant properties are therefore slight.
  • US 2011/0135940 A1 discloses a fire protection glazing with burglary-resistant properties.
  • the burglary-resistant properties are obtained by means of reinforced silicone films with a thickness of as much as 100 ⁇ m.
  • the object of the present invention was to propose a transparent fire protection glazing with particularly good burglary-resistant properties that overcomes the disadvantages of the prior art and can also be used in antipanic glazings.
  • the negative effect of thick plastic sheets on fire protection was to be avoided.
  • the new transparent, burglary-resistant fire protection glazings with antipanic properties were to be capable of being produced quickly, precisely, and with only very few if any rejects using conventional methods such that no special procedural measures would have to be taken.
  • the invention relates to a transparent, burglary-resistant fire protection glazing having antipanic properties.
  • fire protection glazings is generally understood to mean components that are made of one or a plurality of light-permeable systems that are mounted in a frame with holders and seals.
  • EI fire resistance
  • Such glazings are additionally characterized by the indication of the duration of their fire resistance in minutes (e.g.: EI 30, EI 90, E 30, EI 120).
  • E glazings prevent only the spread of fire and smoke for the corresponding time.
  • EI glazings must prevent the passage of heat radiation.
  • the transparent glazing according to the invention preferably has transmittance in the visible spectral range of at least 20%, particularly preferably at least 50%.
  • a transparent glazing or a transparent component of a glazing can have transmittance in the visible spectral range >70%.
  • burglary-resistant refers to fire protection glazings if they are secure against manual attack and ballistic attack (cf. DIN 1627 ff.). Depending on the protective effect, they are divided into five different resistance classes with increasing protective effect (EH01, EH02, EH1, EH2, EH3).
  • an “antipanic glazing” is understood to be a glass door which can be opened simply in one direction at any time.
  • the glass doors usually have an opening lever which extends readily accessibly over the entire width of the glass door and is actuated by pressure.
  • the opening lever is typically arranged toward the interior such that the door can be opened outward. If a panic occurs in the interior, for example, caused by escaping crowds, the door can be opened in a simple manner at any time in order to open an escape route.
  • such antipanic glazings can be disadvantageous, as it suffices to provide the glazing with a relatively small breakthrough (hole) in order to be able to actuate the opening lever from the outside. Consequently, antipanic glazings should have burglary-resistant properties in order to increase the effort for producing such a breakthrough.
  • the transparent, burglary-resistant fire protection glazing includes at least one, in particular one centrally arranged, burglary-resistant composite.
  • the centrally arranged composite includes at least one transparent plastic pane.
  • the term “plastic pane” means a rigid pane, in contrast, for example, to a flexible plastic film.
  • the burglary-resistant composite includes at least two transparent plastic panes that are adhesively bonded by means of an adhesion-promoting layer.
  • the thickness of the plastic panes is preferably from 1 mm to 15 mm, particularly preferably from 6 mm to 12 mm, meaning the total thickness of the optionally multiple plastic panes.
  • Transparent, impact-resistant technical plastics with glass transition temperatures above 100° C. and melting temperatures above 100° C., preferably above 200° C., can be used as plastics here.
  • polycarbonate or polymethyl methacrylate are used.
  • the thickness of the burglary-resistant composite is preferably at least 1 mm, particularly preferably at least 2 mm.
  • the thickness of the burglary-resistant composite is, in an advantageous embodiment, from 1 mm to 15 mm, preferably from 2 mm to 15 mm, preferably from 6 mm to 12 mm.
  • High thickness of the plastic panes improves, in particular, the burglary-resistant effect of the glazing.
  • the thickness of the burglary-resistant composite is advantageously at least 8 mm, for example, from 8 mm to 15 mm or from 8 mm to 12 mm.
  • the adhesion-promoting layers can be adhesive layers or films.
  • films made of plastic are films made of a plastic selected from the group consisting of polyvinyl butyral (PVB), ethylene vinyl acetate (EVA), polyurethane (PU), polypropylene (PP), polyacrylate, polyethylene (PE), polycarbonate (PC), polymethyl methacrylate (PMMA), polyvinyl chloride (PVC), polyacetate resin, casting resins, polyacrylates, fluorinated ethylene-propylene copolymers, polyvinyl fluoride, and/or ethylene-tetrafluoroethylene copolymers.
  • PVB polyvinyl butyral
  • PU polyurethane
  • the adhesion-promoting layer is, in particular, not an intumescent layer, but instead serves only for the bonding of two panes.
  • the thickness of the adhesion-promoting layers is preferably from 0.3 mm to 5 mm, particularly preferably from 0.76 mm to 2.5 mm.
  • the burglary-resistant composite comprises at least two plastic panes and at least one glass pane. This further increases the burglary-resistant effect.
  • the glass pane is arranged between the two plastic panes, and, for example, is bonded thereto via adhesion-promoting layers. This further increases the stability of the burglary-resistant composite.
  • the glass pane can be thermally or chemically tempered to further increase break resistance.
  • a composite pane i.e., at least two glass panes bonded to one another via a thermoplastic intermediate layer, can also be arranged between the plastic panes.
  • the burglary-resistant fire protection glazing further includes at least two, in particular two, fire protection units arranged on both sides of the centrally arranged burglary-resistant composite.
  • the fire protection units preferably have in each case an outer surface that delimits the fire protection glazing.
  • the burglary-resistant composite negatively affects the fire behavior of the glazing due to its high plastic content (high fire load).
  • the fire protection units arranged on both sides the burglary-resistant composite is protected in the event of fire such that it cannot catch fire or only does so after a significant delay. This is the major advantage of the present invention.
  • Each fire protection unit comprises at least two, in particular three, glass panes adhesively bonded by means of a transparent, intumescent layer.
  • the fire protection units can in each case have the same number or different numbers of glass panes. Preferably, they have the same number of glass panes.
  • an additional glass pane is arranged between at least one of the fire protection units and the burglary-resistant composite, preferably between each fire protection unit and the burglary-resistant composite.
  • the bonding is again preferably done via adhesion-promoting layers.
  • the fire protection units are, in each case, connected via at least one, in particular one, additional glass pane to, in each case, a side surface of the centrally arranged, burglary-resistant composite by means of at least one, in particular one, of the above-described adhesion-promoting layers.
  • the glass panes are adhesively connected to the burglary-resistant composite by means of at least one, in particular one, adhesion-promoting layer.
  • the centrally arranged, burglary-resistant composite is connected to the two additional glass panes.
  • One of the additional glass panes that are positioned opposite one another is adhesively connected by means of at least one adhesion-promoting layer to the first fire protection unit with the first outer side and the other one of the additional glass panes that are positioned opposite one another is adhesively connected by means of at least one adhesion-promoting layer to the second fire protection unit with the second outer side.
  • the advantage of the additional glass panes resides in the increase in glass content and, thus, in the resistance of the fire protection glazing.
  • the glass content could also be obtained by enlarging the fire protection units by additional glass panes, which is, however, more expensive due to the additional intumescent layers.
  • the glass panes of the fire protection glazing and in particular of the fire protection units are made of at least one glass, selected from the group consisting of flat glass, float glass, quartz glass, borosilicate glass, soda lime glass, and ceramic glass.
  • the fire protection units are made of soda lime glass.
  • the thickness of the glass panes is preferably from 3 mm to 15 mm, particularly preferably from 3 mm to 8 mm. This refers to the thickness of each individual glass pane.
  • the transparent, intumescent layers are made of alkali silicates and/or of salt-filled aqueous acrylic polymers.
  • alkali silicates are used, in particular sodium silicate.
  • suitable transparent, intumescent layers are found in international patent application WO 2007/11887 A1.
  • the thickness of the intumescent layers is preferably from 2 mm to 8 mm, particularly preferably from 3 mm to 6 mm.
  • the fire protection glazing and in particular the fire protection units can be stabilized against UV radiation.
  • suitable stabilizers are known from German patent application DE 10 2005 006 748 A1 and European patent application EP 1 398 147 A1.
  • the invention also includes an antipanic door, containing a fire protection glazing according to the invention, preferably arranged in a frame system, and a one-sided opening mechanism that is suitable for opening the antipanic door in one direction at any time and in any locking status, in particular an opening lever.
  • the opening mechanism is arranged on the interior side toward the room or building closed by the door and the door typically can be opened outward.
  • the transparent, burglary-resistant fire protection glazing is produced by constructing a laminate composite by precisely superimposing the individual planar pane elements and introducing them in the bag process into an autoclave furnace and adhesively bonding the pane elements at elevated temperature and pressure (cf. German patent application DE 10 2010 037 966 A1, page 4, paragraph [0021]).
  • the transparent, burglary-resistant fire protection glazing can be used in many ways.
  • it can be used as a movable or stationary functional and/or decorative single piece and as a built-in component in furniture, appliances, buildings, and means of transportation.
  • it is used where there is a high risk of burglary associated with a high risk of fire.
  • it is used as an architectural construction element (in particular as a component of a glass door or a stationary glazing) in buildings, such as museums, banks, airports, terminals, or railway stations, where large crowds develop and/or valuables, expensive goods, works of art, or hazardous materials are used or stored, particularly preferably as antipanic glazing.
